[ROUNDTABLE] Tyre 'Cliffs' Update

OK this is how I see it so far

We've done 3 races, 100% distance and no refueling.

First race-Mexico 14 degrees (dry)

Our leading team failed to finish the race due to temperature drop off being ridiculous at around 70% (remaining) and needing to increase push level.

The team second in the championship switched to SS to try and limit the damage and limped across the line in 3rd/4th they also experienced similar issues.

Second race-Brazil can't remember temp (wet)

No real issues here but teams complained it was impossible to know fuel loads from practice results and what push level would be required

Third race-China 33 degrees (dry)

Again leading teams complained it was impossible to guess fuel load and they overfilled again. Soft and medium tyres behaved sensibly with temp drop off but it was 33 degrees, I didn't use them but hard tyres seemed to be useless as they cooled way too quickly.

In conclusion

In a 100% league we're now making too many pit stops and it's mainly guess work with fuel loads, I'm personally worried that as the autumn and winter months approach European races we'll be making even more due to the experience in Mexico.

I'm assuming all our teams tyre economy stat is low at the moment I'm only at 17 points, but if someone could confirm this makes a difference to tyre temperature (not wear) it would be appreciated as this could be an easy fix?

I'd also like to add that two of our top three teams are now taking a break from iGP manager as they are not happy with the changes this seems a bit knee jerk to me but that's their choice. However, I can see me making a similar decision if winter races always echo the issues we saw at the Mexican race. Which was farcical

I've had two races when I've been losing temp before 50%. League is 75% at 2x speed. No refuelling, two tyre rule.

Brazil - 28c. Mediums losing temp around the 60% mark. 
Mexico - 19c. Softs losing temp around 60% again.

Push levels would have been fairly consistent throughout the laps at that stage of the stint(s).

Wouldn't say it was a massive drop off in temps, so manageable but definitely wouldn't have happened before the update.

I think the update is interesting. Resets strategies for most tracks - though we still managed to make a 1 stop at Italy work like before.

Initial reaction was that the update had gone too much the other way, but its the same for everyone so not really a big deal.

I increased TE to about 80 points and I have the same wear of the other teams who have not added any points. On the last version it was cool having TE because it was enough passing from 30% to 33% (1 more lap). Now it's impossible to pass from 50% to 54%. Tell me how is it possible?

As winter is come how we expect to play SS at 5°C in USA or Hungary pitting every lap? As the S is 5 level push all the lap and after 75% S become cold? I would know who thought this s*it. The previous system was good. It would have been enough increasing the tyre wear for compound. This is my last message about. Bye 

How are you guessing fuel loads? Can you not use simple math?

Dario do you primarily play refuelling or no refuelling? Going back to a previous one of your questions as well some of the variance you see in feedback could be due to differences between the two formats.

It’s a little more tricky for no refuelling and there’s a benefit to being lighter over the course of a race so you want to cut it fine. But if you cut it too fine you end up retiring.

With tyres requiring more push levels safety margins have changed for a no refuelling race. And are harder to predict going into an unknown situation right now but that will stabilise.


@Bud I’m not sure I understand your comment?

From my experience of the previous tyre format you couldn’t even overtake a set of older tyres with a 20-30% advantage of if you were stuck in a DRS train with similar fuel levels. But you are saying 3% used to make a difference for you? Or am I misunderstanding?


In general I agree with the concerns that colder weather is going to become problematic and that further work is required. But I still view this update as an improvement on the previous format by a significant margin.

Yes, just having 3% more than my competitors usually gave me benefits. I could make overtakes without boost, or make my stints shorter or longer of 1 lap. Now seems.TE is useless because I am 75 DP in TE and after that I confronted with my mates and there are no benefits. But it's logical. Passing from 50% to 54% means you can pass from 30% to 40% in proportion. And I don't know if in the previous system it would be possible even if you would have put 200 DP in TE.


I think that this update is too much drastic. Devs' aim should be make different strategies balanced. Now there is only a way to make a stint. Old tyre wear was very good one or two years ago don't remember when exactly. Now you have to pit only in one determined lap to make the right call or you lose. I can't imagine in 1 car leagues. How f*** is supposed to work this system in winter where in Hungary S is PL5 all the time?

Oh I've not tried no refueling I don't like the sound of it, I assumed the game gave you enough fuel to finish the race, it's a bit weird that you can run out of fuel on a no refueling race.. ?

Why be so sarcastic when you've not tried it to have accurate knowledge?


This feedback thread is meant for constructive criticism.

Who would have ever guessed you have to manage fuel on a no refueling race ... So I naturally assumed you were racing with refueling. It's a very good assumption to think you do not need to worry about fuel..
For constructive critism and what I think should change is the SS tyres, maybe add a little bit more durability so they can last a couple more laps. This is for refueling and 100% distance.

Technically you didn’t need to manage fuel as game suggests a fuel load however it has a massive safety margin built in (for 75% it is >10 litres so you would seriously uncompetitive (especially as its simple to work out fuel needs taking into account likely push level behaviour).

The issues occurring in no refuelling races since the update are just an example of no adjustments to strategy to take into account new tyre behaviour.

I assume you mean refuelling 100%? Either that or you have successfully bamboozled me.


As others say the game gives you a default fuel load but it’s conservative. You can make a lot of time up by adjusting it. But it’s not as simple as taking your fuel rate and multiplying it by laps which will get you through most refueling races.

I agree that right now the life on SS is a bit short. It’s even worse in no refuelling as well, you don’t get a fuel weight offset to help you travel faster there.

Yeah I'm an idiot, I apologize I did mean refueling lol

@Dario, well I did start my post saying no refueling 

Anyway I think we're getting side tracked with my guess fuel comment. In essence you can just add a bit more to cover it but the "bit more" is hard to judge at the moment until players learn tyre behaviours in certain conditions.

My main concern is that come winter it'll be 5+ stop races on push level 5 just to keep heat in the tyres. If you're racing at 100% distance.

Let's see how it goes, I hope I'm wrong 

Come on gents !!!
This forum is to comment about the new tires "cliffs"

Let's FOCUS on that, please !!!
Thanks in advance !!! ?

The biggest problem so far I think is that on some circuits the operating window of the tyre is the same for S, M and H, you can't take them farther than lap 12-13 laps. The harder compounds may have less tyre wear, but they start to get colder much earlier to the point of no return no matter how much you push. And well, Supersofts are useless espessially in the no refueling league. We'll run the full season I think and I'll have a conclussion, but so far the the only tyre to use is Mediums, maybe sometimes Softs for the first stint, but that's it. I do like the new undercut tho, really makes a difference, and sometimes makes it worth to take that risk. Also all the tyres getting colder with wear happened in 25°c-30°c heat I can't imagine what it's going to look like in the winter months

I can't stop saying Tyler is right... There is no more chance. Only a way to perform a stint. I am curious to see 5 pit stop strategy in Hungary at 5°C ... Yesterday I tried SS in Malesia... Lasted 2 laps.... You deleted a compound 

USA will be the next GP
DP tires from 74 to 193 have No change at all to improve compounds 
SS 8% / S 5% / M 4% / H 3%

DP tires after 74 is useless !!! ?

Again, the % tires wear need changes as well to balance the "cliff" !!!
Am I wrong ???  

What do you mean by "DP" and "74 to 193"?

Bello iGP.
